ArduCopter 2.4 released

Version 2.4 of the ArduCopter code is now available in the AP Mission Planner and in the downloads area. Although not as big a change as the 2.3 release, it still includes a respectable number of enhancements and bug fixes.

improved throttle range in stabilize mode. You may find that it takes slightly higher throttle than previously during hover but hopefully you'll find that you have more useable range of the throttle stick as well.

The default PIDs are optimized for a 3DR/Jdrones quad with 850 motors and 10" props. If you're using more powerful motors/props, start by turning down Rate Roll P in 25% steps.

Thanks go to the numerous contributors including users and their detailed bug reports, developers and testers. Hopefully all together this will add up to a nice smooth release!

As per usual, please post your comments, issues in this discussion. For enhancement requests for future versions, feel free to add them to the issues list. Note: you can "star" an issue to receive emails when someone comments on the item. On the dev side it helps us because we can get an idea as to which feature requests are the most popular by sorting by the number of people how have starred each issue.

Could just be a funny leftover parameter from testing if you didn't erase/reset after loading, or as Robert suggests, the Rx is browning out and acting strange when there is current being pulled by the motors.

Note the small change I edited above, that should be rate P. I can reproduce your problem at will by lowering them to 0.

thanks for the help guys... I figured I would just load the 3dr default parameters....i know have quad that loiters pretty good...and responds to pitch and roll input for rc..... will need some fine tuning but flies good enough to run thru a couple of 5000mah batteries in no time... some 12" props will be in order shortly as the 11's just dont cut it.....
